Did anybody get horns figured with triodes ?

Hi I am new here, out of loop along time, did the horn get figured out with low power or are there better setups available for a life like presentation.

I do not know about now but back a while ago I finally figured out the fewer gain stages the cleaner the sound but how can you run a speaker with less than 5 watts?

Thanks for replies! I love records too!

If you're not bass freak, than other part of sound is sweet. I had diy 6l6(in SET design triode only) based amp 4...5 wpc and was powering JBL 4312 vintage monitors that are 94dB efficient. the bass went down to 48Hz flat and to 41Hz with 5dB slope. I could get 97db/m SPL when turned volume all the way up. The volume control was initially passive but then I decided to use 12AT7 NOS Telefunken single duo-triode for both channels.
The total cost of SET amp and speakers were in $150 ballpark when I built it 15 years ago.
